CHARLES H. LOOP, OF ARKANSAS CITY, KANSAS, ASSIGNOE BY MESNE, ASSIGNTIIENTS,

TO LOOP STEEL LIANUFACTURING 00., A C(JRPORATION OF DELAWARE.

BECEP'IACLE VENTILATOR.

Application filed August 30, 1921. Serial No. 496,8?7.

To all whom it may concern.

Be it known that 1, CHARLES H. Loor, a citizen of the United States of Ai'nerma', and

resident of Arkansas City, in the county of Cowley and State of Kansas, have invented certain new and useful improvements in Receptacle Ventilators, of which the following is a specification.

This invention relates to improvements in receptacles and particularly to closures for same,the said invention having reference more particularly to the provision of novel means for ventilating a receptacle to relieve pressure which may develop within the re ceptacle, and means also for equalizing the pressure between the interior and exterior of the receptacle.

While I have referred to the invention as being adapted for use in connection with receptacles, the mvention 18 shown, 1n the present embodiment, as associated with'an oil tank, and in thefurther description the said receptacle will be referred to as a tank, but it is understood by that term that any receptacle, holder or the like to which the invention can be applied is comprehended within the term.

A still further object of this invention is to produce a tank having a cupola or housing for protecting an openingin the roof or cover of the said tank, the said housing being provided with oppositelyv operable valves opening inwardly and outwardly in order that the pressure inside and outside of the tank may be equalized, novel means being provided for guarding the cupola or housing from access of insects or foreign substances.

With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote correspond- 'ing parts in the several views, and in which- Figure 1 illustrates a sectional view of a tank having a pressure equalizer and a manhole applied thereto Figure 2 illustrates a top plan View thereof;

Figure 8 illustrates a sectional view of the air equalizer and tank protector;

Figure 4 illustrates a sectional view at right angles to that shown in Fig.3;

Figure 5 illustrates a horizontal sectional view on a line corresponding with the line 5-5 ofFig. 3; and

Figure 6 illustrates an end elevation of the housing.

In these drawings 10 denotes a tank which, in so far as its configuration, and other details of construction are concerned, may be of ordinary type,'although 1 prefer that the tank shall have a central post 11 with braces 12 for the cover or roofing 13,'

this latter item being hereinafter referred to as the roofing.

A hole 1 1 is formed in, the roofing and the said hole is covered by a cupolaor housing 15, one end of which has an aperture 16 guarded by a louvered door 17 which is secured in placeby fastenings 18 such as wing nuts. The housing is furthermore shaped to form a flange 19 at the edge of the-opening, which flange forms a frame or seat for a screen 20 of wire cloth or the like, which may be held in place by a gasket 21 interposed between the door and the said flange.

prevent the formation of vacuumtherein,

whereas a valve 28 acts in conjunction with the valve seat '26 and serves to permit the escape of air from the tank, should pressure greater than atmospheric pressure develop within thetank.

By means of the mechanism and the arrangement of parts illustrated, it will follow that air may enter the casing and it would be free to circulate into the tank, should the pressure from without be greater than the pressure from within the tank, and likewise air would escape from the tank past the valve 28, should the pressure within the tank become abnormal.

The construction of a device in accordance with this invention will prove coinparatively inexpensive and it can be attached to tanks now in common use by the simple expedient of cutting a hole in the roofs of tanks and securing the housing on the roof thereof to protect the said opening.

The opening 30 which is formed in the roof of the tank may have a suitable flanged ring 31 surrounding it, to which a cover 3% is applied, and the cover may be secured in place by hinges 35 and a fastening 39 oi appropriate type, but these features do not form the subject of claims in the present application.

I claim:

1. In a ventilator for tanks, a tank hav ing a roof, the said roof having an aperture formed ther in, a partitioned housing applied to the roof and accessible on one side of the partition to the interior of the tank through the opening, the said housing being in communication with the atmosphere on the side of the partition opposite that in communication with the tank, the said partition having passages therethrough, valve seats on opposite sides of the partition at the edges of the openings, the said valve seats being oppositely inclined upwardly toward the partition, and hingedly mounted oppositely I operable valves engaging the valve seats and controlling the said passages.

2. In aventilator for tanks, a tank having an apertured roof, a housing having a partition with a chamber on each side of the partition, one of said chambers communicating with the interior of the tank through the opening in the roof, the wall of the cusing of the other chamber having an aper ture therein opening to the atmosphere, a flange at the edge of said opening, a screen seated against the flange and guarding the opening, a ventilating door guarding the opening, the said partition having passages therethrough for establishing communication between the chambers, and oppositely operable valves "for controlling the said pas-. sages.

3. In an oil tank having an apertured roof, a housing having a vertical partition therein dividing the said housin into compartments, one of which communicates with the interior-of the tank through the opening in thereof, the said partition having openlngs therein, a valve seat on one side of the partltion in one otithe said chambers,

a valve seat on the opposite side of the partitlon in the other chamber, valves on the said valve seats and means for oscillatably mounting the said valves, the said casing having an aperture communicating'with the atmosphere and with the chamber opposite that in communication with the tank, and means for guarding the said aperture.
